Ces données peuvent être une clé de sécurité ou u identifiant. L'émulation d'un transpondeur RFID actif consiste à faciliter la sélection de données et d'instructions d'émettre par un utilisateur. L'émulation d'un transpondeur RFID passif consiste à détecter la présence proche d'un lecteur RFID. Dans un cas comme dans l'autre, la fourniture de données à un dispositif de communication peut comprendre un ou des attributs de signal associés.
